How much neodymium iron boron is used in new energy vehicle motors?
2 Answers
New energy vehicle motors require 13 kilograms of neodymium iron boron, with a demand that is more than 4 times that of traditional vehicles. Introduction to new energy vehicles: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources, integrating advanced technologies in vehicle power control and driving systems, resulting in advanced technical principles and featuring new technologies and structures. Classification of new energy vehicles: New energy vehicles include four major types: hybrid electric vehicles, pure electric vehicles (including solar-powered vehicles), fuel cell electric vehicles, and other new energy vehicles. Unconventional vehicle fuels refer to fuels other than gasoline and diesel.
The usage of neodymium iron boron magnets in new energy vehicle motors actually varies quite a bit. For common small cars, it's typically around 1 to 1.5 kilograms, while for high-performance vehicles or SUVs, it can reach 2 kilograms or even more. As someone who loves studying automotive technology, I know this material is used to improve efficiency—for instance, permanent magnet synchronous motors rely on it to generate strong magnetic fields, enabling quicker starts and better energy savings. Of course, the exact quantity depends on the motor's power output; those below 100 kilowatts may use less, while those above 150 kilowatts require more due to higher magnetic demands. Additionally, the battery system also affects this, with dual-motor layouts consuming more material. Nowadays, automakers are experimenting with weight reduction using composite materials, which for everyday drivers could mean slightly lower costs. But don’t worry about battery safety—regular vehicle check-ups are always a good practice.
